The tripod antenna mount you have will be fine. I am not recommending that you buy a different antenna mount.
The information is provided as practical useful information. It is better to have practical and useful information then no information at all.

The VHF high band channel is WTVI Real channel 11 Virtual channel (42.1) .

The Real channels that are received by the Tv antenna and the Virtual channels are identified in the tvfool radar report collums under the headings of , Real and (Virt).

Virtual Channels are in most cases , the Analog channel number and analog channel that the Tv station was transmitting on before the change to Digital transmission.

Some Tv stations kept the old Analog channel number , the reason is Channel Branding , the Tv station has been using a number for many years so they keep it even though the Tv station may be transmitting on a different digital channel now.

As to the CS2 or CS4 I stated what they are and as to the CS2 Complete I stated what it is.
Other Advisors can give there recommendations if they choose.
As always you can choose the course of action on what you think is best.
